Even behemoths have their little problems. People love to shop for Christmas presents at Walmart, but they forget that they can buy their trimmings there too: the ribbons, the lights, the gift wrap. So they go spend 6 billion dollars on this stuff at Walgreens.
I worked with one of Walmart's agencies to create this spot while writing and producing an original Christmas carol that had to sound like a real Christmas carol. And, by golly, sales tripled. The next time somebody tells you the TV spot is dead, show them this.
